Commissioning
o Follow safety instructions.
o Connect mains plug.
o Connect TIG welding torch cable to adapter cable,
attach the cable to the minus terminal of the
equipment and lock by turning to the right.
o Insert earth cable in plus terminal and lock by
turning to the right.
o Attach gas tube to argon welding regulator.
The required rate of flow is 3 - 10 l/min.
o Turn on main switch.
o Tilt selector switch to TIG operation .
o Adjust welding current (the standard value may be
found in the table) on the welding current poten-
tiometer .
o Open gas valve on torch.
o Place torch with gas nozzle on the workpiece so that
a distance of 2 - 3 mm is maintained between the
electrode end and the workpiece.
o Tilt the torch with the gas nozzle slowly until the
tungsten needle touches the workpiece.
o Ignite the arc by carefully lifting the torch.
o Start welding.
o Stop welding by increasing the distance between
the torch and the workpiece, thereby breaking the
arc.
